What event characterized the Paleozoic era?

Answers

The  phanerozoic geologic era is divided into three and the paleozoic era is the first among them. The paleozoic era occurred about 902 million years ago and it divided into six different periods. It was a time of dramatic changes in term of climate, geology and evolution.  
During the first period of the paleozoic era large number of creatures evolved, this is called Cambrian explosion. Most of the biological classes that are still prevalent today such as primitive fish and coral were evolved during this era. Mass evolution of fish also occured during this era. 

The event that characterizes the Paleozoic era is the Cambrian explosion, according to which a large number of biological class prevalent today are primitive of fish and corals that evolved during that era.

Further Explanation:

The Paleozoic Era is run from nearly five hundred forty-two million years ago to two hundred fifty-one million years ago; that was the time many changes occur on earth. This era starts with the breakdown of the supercontinent and the formation of a new one. In this era, many plants are developed and also very first animal (vertebrate) found on land. This era is divided into six different periods, namely:

  • Cambrian
  • Ordovician
  • Silurian
  • Devonian
  • Carboniferous
  • Permian

After this, many Paleozoic seas found with blastoid and crinoid echinoderms, rugose corals, tabulate, graptolites, and articulate brachiopods. At the last phase of this era, glossopterids, cycads, ferns, and primitive conifers were present across many landscapes. The Paleozoic mass disappears at the late phase of Devonian and end phase of Ordovician. The end phase of this era is referred to as the Permian period.

Can you become pragnant afrer your periods

Answers

It is possible but it all depends on when your period ends. A few days after your cycle ends that is when your fertility window opens up. And a little over a week after your period ends, that is when you begin to ovulate. This is the best chance for a woman to get pregnant.

Julia is trying to place a duckbilled platypus, lizard, bear, and monkey on a phylogenetic tree. She learns that the duckbilled playpus, bear, and monkey are classified as mammals. She also learns that mammals share a common ancestor with reptiles. Which additional piece of information will be most helpful to Julia to properly build her phylogenetic tree?A. The platypus has fur like other mammals
B. The platypus lays eggs like a reptile.
C. The platypus does not have fins like a fish.

Answers

The additional information required is that the platypus lays eggs like a reptile.

What are mammals?

The animals classified as mammals are those animals that give birth to their young ones alive and also possess the mammary gland. As such, they can breast feed their  young ones.

Since the mammals share a similar ancestry as the reptiles, the additional information that Julia requires is that the platypus lays eggs like a reptile.

What differences would you expect to see in a population made up of individuals whose chromosomes experience crossing-over frequently compared with a population made up of individuals whose chromosomes do not cross over? Explain your reasoning.

Answers

For the answer to the question above asking what differences would you expect to see in a population made up of individuals whose chromosomes experience crossing-over frequently compared with a population made up of individuals whose chromosomes do not cross over? My answer is that I'd expect a larger gene pool and more diversity in the population whose chromosomes frequently cross-over or much more genetic variability. 
for example different phenotypes are most likely exhibited.
